Waterretention

Hey :) I usually have a very long cycle, about 40-45 days. That's quite nice to skip bleeding so often but the backside for me is that two weeks before I swell lika a sponge 😅 I accumulate a lot of water weight, nothing fit and I feel really uncomfortable. I am very sportive, athletic even, doing crossfit 5-6 times a week. Usually the water disappears 2-3 days into my period, but not this time. I'm on my 7th day and still feel swollen (not as bad but still). Has someone else experienced it? And when did you get back to your "normal you"?
